Four blasts have injured at least 12 people in the Ukrainian city of Dnipropetrovsk, according to government sources.
Yulia Yershova, emergency situations ministry spokeswoman, said the first blast went off at a tram stop at 11:50am
(08:50 GMT) on Friday, injuring five people.
"The bomb seemed to have been placed in a rubbish bin just next to a tram stop near the opera house. That blast
went off when a tram went by," Al Jazeera's Sue Turton said, reporting from Moscow.
The second explosion happened 30 minutes later next to a cinema, injuring seven people, the emergencies ministry
said in a statement.
The third blast wounded three people near a railway station. The government confirmed that a fourth blast hit the city,
but more information was not available.
Vitaly Zakharchenko, interior minister, said he was urgently flying to Dnipropetrovsk to investigate the blasts.
"The prosecution have announced that a terrorist investigation will be held," our correspondent said.
